MAGAZINE PLATE-HOLDER.

Application filed January 3, 1901. Serial No. 41,966. (No model-l To all wiwnr it new concern.-

Be it known that I, ARL PAUL GOERZ, a citizen of the Kingdom of Prussia, and a resident of Friedenau, near Berlin, Germany, (whose post-office address is Rheinstrasso id/46,) have invented certain new and useful Improvements in MagazinePlatellolders, of which the following is a specification.

This invention relates to a new and im proved package for dry-plates andspeciallyconstructod repeating plate-hold be used with the plates thus packed, this combination affording the possibility of loading, unloading, and reloading the plate-holder in daylight.

In the accompanying drawings, Figure l is a view of the new package. Fig. 2 is a crosssection through same. Fig. 3 shows the repeating plate-holder unloaded in a longitudinal section; Fig. at, the same in cross-section loaded with a pack of plates. Fig. 5 is a longitudinal section through the plate-holder under the same conditions, the slides of the plate-b0 ready for removal. Fig. 6 shows the same with the plate-box slides removed. Figs. 7 and 8 show the way of changingplates. Fig. 9 is a cut through line B B of Fig. 5, showing the removable lid of the repeating plate-holder seen from below and the means for light-tight closing the slots designed for the plate-bot; slides after the latter have been removed.

A certain number of dry-plates a or films are inserted in plate-holders Z) of a light and cheap material (sheet metal, celluloid, pressing-board, or ihelike) and inolosedin a frame 0, of a like material, open at both sides. Ribs are provided on this frame to guide it properly when inserted into the repeating plateholder. This frame is closed at the top and the bottom by slides (Z and c, of light-tight material, inserted in appropriate grooves of the frame. On one side these slides project over the side of the frame, so as to form handles. These packages of plates or films are to be used in combination with a repeating plateholder of any known construction, the only condition being that one of the side walls of this plate-holder be replaced by a lid f, Fig. 3, which may be removed and the interior of the repeating plate-holder be made accessible. After removing this lid the plate-box is inserted in the plate-holder. In replacing the lid f the handles of the platabox slides (Z and c are allowed to pass and project through slots g, arranged in thelid, Fig. 5. After the repeating plateholder has been thus closed the slides (Z and c are removed by way of the slots in the lid and the plates are left uncovered in the plateholder, Fig. (5.

To prevent light from entering through the slots g in the lid 1', means are provided to close these slots as soon as the plate-box slides have been removed. To ofect this, sgringgoverned bands 2', covered with velvet naybo arranged on the bottom side of the lid f near the slots After the plate-box slides (Z and e have been withdrawn the bands '4' are pressed against a fixed band covered with velvet, thus closing the slot without in the least prohibiting the reinserting ofthe slides d and e.

The dates may be brought into the focal plane and exposed in the usual way. In the repeating plate-holder shown in the accompanying drawings the repeating plate-holder consists of two boxes Zr; and Z, the latter one being inserted into the former one in a wellknown manner and gliding in it. One of the short narrow sides of the box Z is provided with a handle, while the side opposite to it and the top side are entirely removed. After the lidfhas been opened the plate-box is inserted in the interior box Z of the repeating plate holder, springs .2, fastened inside the box Z, retaining the platebox. After the slides d and e have been drawn springs in, fastened to the bottom of the sliding box Z, pressing .against the plates from below, carry the whole pack upward until the top plate on eonnters the frame-like top of the box Z5, 6. If the sliding box Z is now withdrawn from the box 70, Fig. 7, the top plate is retained by a bandn, fastened to the top of box 7;. As soon as the box Z, carrying the other plates with it, has been entirely withdrawn the top plate falls down to the bottom of box 7;, Fig. 8, and in pushing the sliding box Z in again places itself between the springs m and the bottom plate. When the sliding box Z is withdrawn, a flexible slide 0, fastened to the band n, serves to cover the sliding box and the plates contained therein. The slide 19, forming the top of box L, is withdrawn whenover a plate shall be exposed. To replace the plates after they have been exposed by fresh ones, the slide e is firstinserted through the lower slot g, the springs m being compressed and the plates receding far enough into the frame 0 to allow of the other slide d being inserted in its turn. After removing the lidf and loosening the springs z the plate-box is withdrawn and a fresh oneinserted.

Having thus fully described the nature of my invention and how the same is to be performed, what I claim is Inamagazine plate-holderthe combination, with a flat box, open at one of its narrow sides, having in its top side a removable shutter, closing a window-like opening therein, of a fiat frame of U shape, inserted with its open end ahead into the aforesaid box, a flexible shutter fastened to said box and sliding in 1 cover being provided with automatically-closing slots, adapted to permit the removal and insertion of the shutters of said casing; substantially as and for the purpose described.

In testimony whereof I'aflix my signature 30 in presence of two Witnesses.
